Because for one sakurai, the creator of smash was going under loads of stress working in the game. It was tithe pint where it was affecting his physical and mental health.

Sakurai wanted to end the smash series because it was too hard on him. Especially since melee. But he pushed inward because it was a great creation he had made and wanted to make people happy. He is the reason why Super smash bros is as big and popular as it is now

Not only that but it releases this year. No one expected another new smash game for another few years.
